Rapid a1c test kit

Change in mean HbA_1c from baseline to immediate post-intervention (9 weeks) was the primary outcome of interest. HbA_1c was assessed through finger prick blood collection using a Rapid A_1c test kit and Siemens DCA Vantage Analyzer. Control for use of medication prescribed to lower blood glucose was incorporated into each analysis of the study. These medications were coded as Yes/No based upon participant’s self-reported use.

All biometric data collection was completed by trained research staff and included HbA1c and BMI. To measure HbA1c, study staff used a finger stick blood collection and received results using the Rapid A1c test kit and Siemens DCA Vantage Analyzer. BMI was calculated using height and weight measurements collected by trained research staff, using a calibrated scale. Participants were weighed without shoes and in street clothes.

Family members consented to provide the same measures collected from primary participants: A1c was assessed through finger prick blood collection, using a Rapid A1c test kit and Siemens DCA Vantage Analyzer; fasting glucose was assessed using a glucometer; weight was measured in light clothing to the nearest 0.5 lb (0.2 kg) using a calibrated digital scale; height (without shoes) was measured to the nearest 0.5 cm using a stadiometer; and blood pressure was measured using a sphygomometer and stethoscope with participants seated and arm slightly raised. Physical activity over the past month was assessed by a seven-item Rapid Assessment of Physical Activity (Jiang et al., 2016 (link); Topolski et al., 2006 (link)). Food intake over the past month was assessed through a 16-item food frequency questionnaire (Teufel-Shone et al., 2015 (link)). The study protocol and fidelity monitoring ensured consistency in data collection.
